GT 302 info

Phillip marvetz · 12-28-2012, 02:10 AM

I have a friend with a 66 merc Caliente that wants to run super stock, I'm thinking the GT 68 merc 302 four barrel is the way to go. What carb is legal with this combo?

Mercury 302 used a little Holley. 1.563 throttle bores, 1.250 primary venturi, 1.313 secondary venturi. Like a "600 Holley" or a model 1850. The factory id was C8OF-D for stick, C8ZF-B for an automatic according to the NHRA tech info. The same engine in a Mustang used an Autolite/Motorcraft model 4300 carb.

Finding a original carb would probably be difficult, Would a 1850 holley be a legal substitute?

As long as the throttle bores and venturi size are within the specs of the tech sheet, yes.

Talk to Quick Fuel. If they don't have it, they may make it and put it in their catalog.

We happen to have a J code 302 Holley that is race ready sitting on the shelf. I just cant say for sure if Dad would want to part ways with it. Its just that good of a carb.
